Branching fraction measurement of the decay $B^+ \to \psi(2S) \phi(1020) K^+$ / LHCb Collaboration
The branching fraction of the decay $B^+\to \psi(2S)\phi(1020)K^+$, relative to the topologically similar decay $B^+\to J/\psi \phi(1020) K^+$, is measured using proton-proton collision data collected by the LHCb experiment at center-of-mass energies of 7, 8, and 13 TeV, corresponding to an integrated luminosity of $9\,\mathrm{fb}^{-1}$.

Development of systematic uncertainty-aware neural network trainings for binned-likelihood analyses at the LHC / CMS Collaboration
We propose a neural network training method capable of accounting for the effects of systematic variations of the data model in the training process and describe its extension towards neural network multiclass classification. [...]

Antiprotons and Elementary Particles over a Solar Cycle: Results from the Alpha Magnetic Spectrometer / AMS Collaboration
We present results over an 11-year Solar cycle of cosmic antiprotons based on 1.1×106 events in the rigidity range from 1.00 to 41.9 GV. The p¯ fluxes exhibit distinct properties. [...]

Solar Modulation of Cosmic Nuclei over a Solar Cycle: Results from the Alpha Magnetic Spectrometer / AMS Collaboration
We report the properties of precision time structures of cosmic nuclei He, Li, Be, B, C, N, and O fluxes over an 11-year solar cycle from May 2011 to November 2022 in the rigidity range from 1.92 to 60.3 GV. The nuclei fluxes show similar but not identical time variations with amplitudes decreasing with increasing rigidity. [...]
